Nutrient Cycling in Terrestrial Ecosystems
The first part of the book presents the fundamentals of nutrient cycling. Topics included are cycling of carbon, nitrogen, phosphorus, sulphur and micronutrients. The second part discusses nutrient cycling at an ecosystem scale, covering cropping systems, pastures, natural grasslands, arid lands, tundras and forests. The final chapter reviews current models of nutrient cycling.
Nutrient Acquisition by Plants : An Ecological Perspective
Adaptation and evolution of terrestrial plants depend, to a large extent, on their ability to acquire nutrients. This is a modern and integrative treatment of the mechanisms controlling plant nutrient uptake and how plants respond to changes in the environment. The following key topics are covered: soil nutrient bioavailability; root responses to variations in nutrient supply; nitrogen fixation; regulation of nutrient uptake by internal plant demand; root characteristics; kinetics of nutrient uptake; root architecture; life span; mycorrhizae; responses to climate change. This integrated view helps us to understand the mechanisms that govern present-day plant communities and is indispensable in models designed to predict the response of plants to a changing climate.

Monograph of the Urostyloidea (Ciliophora, Hypotricha)
This monograph is the second of a series treating the hypotrichs, a major part of the spirotrichous ciliates. The urostyloids are characterised by a zigzag-arrangement of the ventral cirri. Like the first part of the series, the Oxytrichidae, it summarises the morphological, morphogenetic, faunistic, and ecological data from the past 230 years, scattered in more than 1300 references from all over the world. Dichotomous keys lead to 36 genera and subgenera comprising 153 species illustrated by more than 2100 figures, including original ones. The treatise offers taxonomists, cell biologists, and ecologists a thorough and up-to-date revision because for each species a detailed list of synonyms, a discussion of the nomenclature and systematics, and an extensive description of the morphology and ecology, including almost all published faunistic records, are provided. With the monographs of the Urostyloidea and the Oxytrichidae the interested scientist can identify more than 320 species of hypotrichs, which are an important component of the eukaryotic microbial life in limnetic, marine, and terrestrial habitats.

Micromammals and Macroparasites : From Evolutionary Ecology to Management
Small mammals are among the most ubiquitous and important components of terrestrial ecosystems. They have coevolved, and now coexist, with a diverse array of parasites, such that not only are all aspects of their biology influenced by parasitism but they also play key roles in the transmission and maintenance of parasitic diseases. This book provides a comprehensive survey of the diversity and biology of metazoan parasites affecting small mammals, of their impact on host individuals and populations, and of the management implications of these parasites for conservation biology and human welfare. Designed for a broad, multidisciplinary audience, it will be an essential resource for researchers, students, and practitioners alike in the fields of parasitology, evolutionary ecology, wildlife management, and conservation biology.
Microbiology of Extreme Soils
This volume provides an excellent introduction to the study of extreme soil micro-biology, and a variety of the challenging and fascinating environments that Earth-bound microbes face. Some are natural, and some are the result of human activity, and all of them have lessons to teach us about life’s adaptations within the “extreme” hori-zons of terrestrial soils. What’s more, each of these chapters (including the chapter on the soils of Mars by Ronald L. Crawford and David A. Newcombe) can give us insights into strategies that may make life possible beyond the safe confines of our present-day biosphere, to other worlds in this solar system and beyond
Methods to study litter decomposition : A practical guide
Decomposition of organic matter is a major ecosystem process involving an array of different organisms, including bacteria, fungi and invertebrates. The main objective of this book is to provide students and laboratory instructors at universities and professional ecologists with a broad range of established methods to study plant litter decomposition. Detailed protocols for direct use in the field or laboratory are presented in an easy to follow step-by-step format. A short introduction to each protocol reviews the ecological significance and principles of the technique and points to key references. Although most methods are described for freshwater ecosystems, many will work equally well in the presented or slightly modified form for studies in marine and terrestrial environments.
Mercury
Mercury, the planet closest to the Sun, is different in several respects from the other three terrestrial planets. In appearance, it resembles the heavily cratered surface of the Moon, but its density is high, it has a magnetic field and magnetosphere, but no atmosphere or ionosphere. This book reviews the progress made in Mercury studies since the flybys by Mariner 10 in 1974-75, based on the continued research using the Mariner 10 archive, on observations from Earth, and on increasingly realistic models of its interior evolution.
Ionospheric multi-spacecraft analysis tools : Approaches for deriving ionospheric parameters

Insects and Ecosystem Function
In the past two decades, an increasing number of ecologists have started to investigate the importance of biodiversity for ecological processes such as energy flow and nutrient cycling, often referred to as 'ecosystem functioning'. Insects are a dominant component of biodiversity in terrestrial ecosystems and play a key role in mediating the relationship between plants and ecosystem processes. This volume is the first to summarize their effects on ecosystem functioning, focusing mainly, but not exclusively, on herbivorous insects. Renowned authors with extensive experience in the field of plant-insect interactions, contribute to the volume using examples from their own work. In addition to providing concise reviews of the field, this volume discusses in detail the advantages and disadvantages of various techniques of manipulating insect herbivory. Thus, the text provides both a theoretical basis as well as practical advice for future manipulative studies of biodiversity-ecosystem functioning.
Human Exploitation and Biodiversity Conservation
The sustainable use of biodiversity is one of the three key objectives of the 1992 "Convention on Biological Diversity". To achieve this, sound conservation practice has to be recognized as beneficial and implemented by all who access, or use it – from subsistence farmers to skiers and pharmaceutical bioprospectors. At the same time, indigenous peoples necessarily utilize enormous numbers of plants, fungi, and fish, particularly for foods and medicines. This book gathers together a wide range of contributions addressing diverse aspects of front-line human involvement in biodiversity exploitation and conservation. Its scope is broad, the organisms explored ranging from birds, invertebrates and mammals – both terrestrial and aquatic – to crops and medicinal plants. Meanwhile, the issues addressed include land use changes, the importance of gardens, hedges and green lanes, housing developments, hunting, invasive species, local community involvement, sacred groves, socioeconomic factors and trade.
